I have a 2013 Accord that I bought in June. Mileage is down from 450 miles per tank to just over 300 under same driving conditions. Any ideas?
Vehicles do use more fuel in the colder temperatures of winter. But that does seem a bit much. Did you switch brands or grades of gas? That might do it. Do you have a locking gas cap? Maybe someone is stealing your gas (no joke). Talk to your Honda Dealer as well. Since this is a new vehicle perhaps something needs adjusting. They may have run into this with other customers. HTH. - Jim
